The bond energies of `F_(2),Cl_(2),Br_(2)` and `I_(2)` are 155.4, 243.6, 193.2 and `151.2 Kjmol^(-1)` respectively. The strongest bond is :

A

`F_(2)`

B

`Cl_(2)`

C

`Br_(2)`

D

`I_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Strongest bond is the one with highest bond dissociation energy.
Highest bond dissociation energy is for `Cl_(2)`.
`therefore Cl_(2)` bond is strongest.
